NECTICUT, A CORPORATION 0F DELAWARE SUCTION FEEDER Application led September 9, 1927. Serial No. 218,398.

Our invention relates generally tothe securing of mold charges from a supply body of molten glass in a glass tank forehearth, extension or 1like glass container, and more particularly to the gathering of such mold charges periodically from the surface' of the glass supply body by suction.

An object of the invention is the provision of a reliable, efficient and otherwise practical apparatus which is adapted to automatically eii'ect the periodic segregation in a suitable receptacle of mold chargesr of symmetrical viscosity, temperature and condition, gathered by, suction from the surface of the body of molten glass, and to periodically discharge such mold charges from the gathering receptacle.

Another 'object of the invention is the provision of a method of obtaining suction gathered mold charges so that their lower ends can bevariably shaped at the time of their separation from the supply of molten glass.

VOther objects of the invention reside in the provision of a fglass suction gathering apparatus of the character described having operating parts capable of adjustment to permit the gathering by` suction of portions of molten glass from a supply body at a levelv tively either as an intermediate station, as into a cullet chute, or at a more distant station,-as at a mold filling station.

Other objects and advantages of the invention will be apparent from the following descri tion, when considered in conjunction with'tlhe accompanying drawings, forming'a part of this application, in which:

The invention provides an apparatus having a gathering receptacle mounted for vertcal'movement through a gathering opening `in the top of a glass container to and from position to gather glass from aV body of molten glass in the glass container. A pair of' r`cooperative -V-not'ched shear blades are provided for -constricting and cutting4 .through the connecting glass between the gathering receptacle and the supply body after the receptacle has been moved upward through the gathering opening. The operation of the shear blades may be timed to cut the connecting glass either during part of the rise of the receptacle or after the receptacle has reached the upper end of its vertical movement, thus permittin variation of the shape of the lower ends o the gathered charges. The shear blades may be operated to close and cut through the rising connecting glass with decreaslng speed, thus securing a further controlof the shape of the lower ends of the gathered charges. The distance from the lower end of the gathering receptacle at which the shear blades will cut through the connecting glass may be varied to vary the weight of the mold charges which may be gathered at different times by the same gathering receptacle. The operating means for moving the gathering receptacle .cullet chute, to a more remote station, such as a position to discharge into successively presented molds on a suitably operated mold table. The gathering receptacle may be stopped at the intermediate station when desired. Suitable mechanism is provided 4for variably controlling the application of suction to the gathering receptacle and for opening and closing the gathering receptacle at the proper times in the cycles of movements of the gathering receptacle .so that molten glass will be quickly drawn .into the gathering receptacle when it is in its gathering position and will be retained therein until the gathering receptacle has been stopped at the intermediate station or has reached the more remote or mold filling station. The gathered charges then'will be discharged from the receptacle.

The means for controlling the application of suction to the gatherin rece tacle is controlled and regulable in epen ently .of the movements of the supporting and operating structure for the gathering receptacle and includes Valves v mounted directly on the gathering head and operable to instantly initiate and stop suction in the gathering receptacle as such valves are opened and closed. The position of the path of horizontal swinging movement of the gathering receptacle can be varied so that the positions of the ends of the horizontal Swingin strokes of the receptacle can beadjusted i required .to compenlsate for varying conditions of service.

The operations of the different operating parts of the improved apparatus may be va.- riablyptimed in respect to one another'to secure suction gathered mold charges of various predetermined weights and shapes under varying conditions and to deliver, such mold charges at a plurality of places selectively.

The invention also contemplates the provision of a novel forehearth or container for the molten glass from which charges are to be' gathered together with a novel and e'ective means for circulating the molten glass in the container so that the gathered charges will have symmetrical viscosity, temperature and condition.

An apparatus embodying the invention may be applied to a forehearth 1 or other glass conduit or container which may be appurtenant to a glass melting tank 2, aspartially shown in Fig. 1. The forehearth 1 is` made of suitable refractory material and preferably is heat insulated by suitable insulation 3, which maybe confined between the forehearth walls and a suitable casing 4, as best seen in Figs. 1 and 4. The casing 4 may be suitably reinforced and supported and may be secured to the walls of the associated tank in any suitable known manner.

The construction of thel forehearth and its connection with the associated melting tank 2 are such that molten glass 5 may iow from the tank under a gate 6 into the forehearth. The gate 6 depends slidably through atransverse aperture 7 in the forehearth to wall adjacent to the juncture of the fore earth with the melting tank and preferably issuspended for vertical adjustment in any suitable known manner, as by the cable 8, so that the glass in the forehearth may be maintained at a desired adjustable level.y

The forehearth top is odset downwardly at 9 in respect to the plane of the remainder of the forehearthtop for approximately half the width of the forehearth and adjacent tov the front of the forehearth4 to produce the external clearance space 10 for a purpose to be presently stated. This downwardly oi'set portion 9 of the forehearth top is provided with a gathering opening 11. The insulation 3 and the portion of the casing 4 which otherwise would extend above the downwardly offset portion of the forehearth top may be omitted.

The approximately longitudinal half portion of the bottom of the forehearth at the side of the forehearth opposite .to that provided with the downwardly offset top portion 9 is inclined upwardly toward its outer side edge as shown at 12 in Fig. 4. An opening' 13 is formed in a side wall of the forehearth structure above the glass level and laterally f erably is formed partly in al removable upper Y lying'portion of said side wall of the forehearth struct re (Fig. 4.) A handle member 15 may be secured to the removable section 5 -14 of the forehearth for convenience in removing and replacing the latter. A glass circulating or stirring implement may be conveniently inserted in or removed from the forehearth when the section 14 has been removed.

l The glass circulating or stirring implement preferably comprises a substantially frustoconical head 16 completely immersed in the glass underneath' the gathering opening 11 anda `stern 17 extending Qbliquely from the ings .the forehearth (see Fig. 1).

glass through the opening 13 in the side wall of the forehe-arth (see Fig. 4) The stem 17Y ofthe glass circulating implement may be carried by a suitable chuck or holder 18 on a shaft 19 which is journaled i`n suitable bearings 20 and 21, respectively,- on the arm of a bracket 22 on a lateral shelf extension 23 of theforehearth casing. The shaft 19 is prevented from moving axially by a collar 24 which fits thereon'between the bearings 20 and 21. The, bearings `20 and 21 have removable cap sections secured to the base portions 'thereof by screws 25 to permit conlvenient assembly of the shaft 19 and its mounting.

- `The inner end` portion of the opening 13 y i preferably ispractically closed by the portion of the stem 17 that extends therethrough such that the upper surface of the substan- J tially frusto-conical head 16 will be tangent toa horizontal plane and will' be located relatively close to the surface of the glass in the forehearth. Rotation of the glass circulatmg implement in the direction indicated by the arrow in Fig. 4 thus will cause a current in the glass of the forehearth at the surface thereof from the Yrear portion of the forehearth underneath the gathering opening because of the adhesive contact of' the upper part of the head 16 with the glass.. At the same time, the contact of the lower por tions of the head 16 and of the immersed portion" of the stem 17 with the glass will cause i sub-surface movement of glass in the 'forehearth laterally and rearwardly from underneath the gathering opening onto the inclined yportion'12 of the forehearth bottom and.

against the adjacent side wall of the forehearth, whence such glass will be deflected rearwandly and laterally toward the ,deeperA lportion of the glass in the forehearth. Effective circulation of the glass in the forehearth past the gathering station underneath the gathering opening thus will -be assuredand stagnation of relatively cool glass in the rfront less heated gases and products of combustion from the forehearth as desired. The temperature within the forehearth may be further regulated by supplying heat tov the forehearth by means of a burner or burners arranged to discharge into the forehearth through a suitably located opening or openas indicated at 28, in a wall or walls of A Vgathering head generally indicated at 29 is carried atone end of an arm 30 which is firmly secured at 31 to the upper end portion of a vertical shaft 32, as best seen in Figs. 2 and 4. The shaft 32 extends through vertically aligned openings 33 and 34 in the top and bottom, respectively, of a substantially rectangular case 35. l The case 35,is supported in any suitable known manner, as by supports 36 adjacent to the portion of the forehearth that is provided with the clearance space 10 and the gathering opening 11. The gathering head may be moved vertically above the gathering opening 11 by axial movements of the shaft 32 between the full line and dotted line positions shown in Fig. I4 and also may be swung between a vposition above thegathering openingand a position laterally of the forehearth for purposes to be presently described by turning the shaft 32 angularly about its axis. The shaft 32 is 'ournaled in the opening 34 and yextends slid.- ably through a collar 36. The collar 36 is disposed in the case 35 and has its upper end portion journaled inthe opening 33 and its lower end portion journaled in an opening loo 37 in an inwardly extending bracket arm 38 tends into. a tubular housing or cap 40 that is secured` at its upper end to the'bottom' of the case 35 and may have its upper end portion or head formed toprovide an additional bearing at 41 for the shaft 32.

The mechanism for moving the shaft 32 vertically comprises a lifting arm 42 having` a fork 43 at one end arranged to straddle the shaft 32 and pivotally connected at 44 to the upper endsof a pair of links 45'which in turnare lpivotally connected at their lower ends by means of the trunnions 46 toa collar 47. Y The collar 47 is rotatably held between Vthe vertically spaced anges of a collar 48 which is. secured to the shaft 32 in -any suitable known manner, as clearly shown in Figs. 4 to 7 inclusive. The lifter arm 42 is pivotedat its other end on a horizontal pivot l A bolt 53 carried by the arm 42 extnds loosely through an opening in the end portion 52 of the lever 51 with which it is connected adjustably by the nuts 54 and 54 whichrespectively engage the bolt 53 above and below the end portion 52 of the lever 51. The other arm of the lever- 51 is pivotally connected by a rod 55 with one end of a lever 56 which is vfulcrumed at its other end on a horizontal pivot element 57 in the lower part of the case 35, the rod 55 extending loosely through an aperture 58a in the top of the case 35. The lever 56 carries a cam roll 58 Which bears against the working.

edge o f'a cam 59 that is disposed in the case 35 on a horizontal cam shaft 60. The. cam shaft 60, which is driven as hereinafter stated, is journaled in-bearings 61 and 62 in the front and rearwalls, respectively, of the case 35. The ends of the cam shaft project from the case for purposes which will presently appear. The contact of the cam roll 58 with the cam 59 is below the level of the cam shaft'60 (see Fig. 4) so that the lever 56, which maybe slightly bent or angular in shape, as shown, will be oscillated vertically as the cam 59 turns about the axis of the` shaft 60, thereby causing a corresponding oscillation of the lever 51 and the lifter arm 42 as a unit and thus moving the carrying ,arm 30 with the gathering head thereon veri tically. The path of vertical movement of the gathering head may be adjusted ver- -tically by adjusting the nuts 54 and 54 to vary thedistance between the endportion 52 of the lever 51 and the arm 42 and to thereby adjust thel lower limit of the cam controlled (vertical movement of the gathering head.

. The horizontal swinging movement of the carrying arm 30 results from rocking Vof' the shaft 32about its axis. The rocking of the shaft 32 inone direction is effected lby mechanism comprising 'an' adjustable spring cushioned'link 63 (see Fig. 4) that is connectedfat one end by a. vertical pivot element 64 to' a rocker arm 65 which is integral: withv the collar 36. The other, end of the link 63 is connected by a horizontal pivo't element 66 to theupper end of a lever 67. The lever 67 is fulcrumed at its lower endon a horizontal pivot element .68'that is supported on an upstanding,bracketarml 69. on the bottom lof a coil spring 78, to be presently described.

The lever 67 thus will be oscillated about the link 63, the rocker arm `65`^and the'collar 36 to the shaft 32, which will be' `rocked .abgutf lhorizontal pivot 68` as'rthe cam 71 rotates: and motion will be imparted through the The cami71 is formed to actuate the lever I 67 so as to cause in each cycle of rotation of the cama horizontal swin g movement of the gathering head from the position above the gathering opening lljshown in Fig'. 2 and by the dotted lines in' Fig. 4 toward a mold' charging position b eyondj'the fronte d of the forehearth and above a mold tab e 72, indicated by the dotted lines in 3.C

In traveling from the full line position to the dotted line position of Fig; 3, the gathering head passes across an intermediatestation which is re resented by the culletchute 73 of Fig. 3 and)` the` gathering head may be halted at such intermediate station without stopping the cam 71 or effecting any manual adjustment of the motion transmitting means between the-cam 71 and the shaft 32. This is possible because of the construction of, e link 63 which is best seen in Fig. 4. link 63 includes the slidably co-engaged telescopic sections 63@ and 635, respectively, and the compression spring 63o which is located within the section 63a around the section 635 between a head 74 on an inner end of the section 635 and an inwardly extending flange leo 75 on the inner end of the section 63a. The

section 63a is tubular in form. Consequently, as the lever 67 is swung on its fulcrum away from the axis of the cam` shaft 6,0"as

the cam 71 rotates, the resultant pull on thej-f section 63a ofthe link 63 will-'be communi- 635 of the-link 63 and thence through the rocker arm 65 to the shaft 32. The shaft 32 ,cated through the spring 63e to the section thus will be rocked as required to swing the r gathering head from a position above the gathering opening toward the mold filling position but such swinging movement of the gathering head may be stopped at the inter- 30 between the full line and dotted line positions ofI Fig. 3,. the stop 76 must be moved to and maintained in its retracted or non-obstructing position .by

'125 stood that in order to permit swinging move- ,ments of the amechanism which will be presently described.

after the arm 77 strikes the stop 76 will com- Athe gathering head is press the spring 630 and thus elongate lthe link 63 without injury to the motion transmitting mechanism between the lever 67 and the shaft 32. rlhe arm 77 is connected by the afore-mentioned coil spring 78 to an anchoring member, such as the bolt 79 thatis threaded through the rear wall of the case 35. The spring 78 thus will be placed under tension as the gathering head swings laterally outward from its position over the gathering opening and therefore will return the gathering head to position over the gathering opening as soon as the contact of the cam roll anchoring member 79 can be adjusted in the opening in the wall ofthe case 35 through which it 'extends to vary the tension on the spring 78 when the gathering head is over the gathering opening. c A nut 80 is provided on the outer end portion of the bolt 79 to bear against the rear wall of the case 35 for locking the member 79 in position. The pivotal connections-of the outer ends of the sections 63a and 63?; of the link 63 with the lever 67 and the rockerarm 65, respectively, are effected through the agency of couplings 63d and 63e as clearly shown in Fig. 4. rlhe coupling 63e comprises a pair of pivotally connected members, the inner of which is pivotally attached to the section 635 and has a stop shoulder 250 formed thereon adapte to engage with theinner end of the section 63a so as to limit the overlap of the section 63a on the section 63?). The coupling 63d likewise comprises a pair of pivotally connected members, one of which has a portion 251 threadedly engaged withthe outer end portion of the section 63a, The section 63a may have a non-circular or nut portion 252 adapted to be gripped and turned by the iiners of a hand ora suitable tool so as to ad- ]ust the threaded connection between the section 63a and the coupling 63d. The effective length of the link 63 thus may be varied within limits with consequent change' of position of the path of horizontal swinging move.- ments of the gathering head 29.

The shape of the cam 71 also is such that ermitted to remainin line with the gathering opening 11 for a substantial part of the cycle of rotation of the cam, then is swungquickly outward to the mold filling station if the position of the stop 76 will permit, then is permitted to remain at the mold lling station for part of the cycle of rotation of the cam and finally is returned quickly from the mold filling to the with the cam 71 will permit. Theu position above the gathering opening during the final part of the cycle of rotation of the cam.

The stop 76 is carried on the outer end of a stem 225 projecting from a piston 226 in a cylinder 227 (see Figs. 3 and 12). The cylinder 227 is, carried at one end on an apertured wall of the case 35 so that the stem 225 extends into the case 35. The stop76'will be disposed in the path of movement of the arm 7 7- when the piston 226 is maintained at the inner end of the cylinder 227 and will be Y disposed out ofthe path of movementof the arm 77 when 'the piston 226 ismaintained at the outer end ofthe cylinder 227. As shown in Fig..12, pressure fluid may be supplied throu h the pipe 228 to the inner end'pf the cylin er 227 to 'maintain the piston 226 at the outer end of the cylinder 227 and thel stop 76 in its inactive position until a three-way valve 229 in the pipe line 228 has been actuated to shut od the supply of pressure liuid to the inner end of the cylinder 227 and to release the pressure therein. Ak spring 230 -in the outer end of the cylinder 227 then-will be effective to move the piston 226 to the inner end of the cylinder 227 and to maintain d tends and is connected intermediate its length with an elbow 86 (see Fig. 9). The elbow 86 is connected by a suitable coupling 87 with a flexible tubing 88 that in turn is connected with a pipe 89.- The latter is adapted `for connection with any suitable source of suction and is best seen in Fig. 12. The eX- tending end portions of the tube serve as pivotal supports for pairs of ears 90 and 91 on complementary substantially semi-circular attaching plates 92. The attaching platesl 92 are secured by cap bolts 93 or like fasten- 1n siilar half portions 95 of an inverted cup shaped holder for a two part inverted cup shaped gathering receptacle. The i latter comprises The sections of the gathering cup preferably 'are made of brush' carbon or like graph1te composition material such as is disclosed in the co-pending a plication of Karl E. lfeiler, filed July 5, 192 Serial No. 203,391. Nuts 97 on the ends of the tube 85. prevent axial movement of the tube 85 relatively .to the body 81. The ears 90 and 91 on the extendingi cuter end portions of the tube 85 are prov1 e devices to the ianged head portions 94 ofthe longitudinal half sections 96.A

with upturned lugs 98 which respecl tively are located at oppositersides of the axial lineof the tube and are connected pivot-ally at their upper ends by links 99 with the opposite ends of a cross head 100 on a' stem 101. The stem 101 extends from a piston 102 in the cylinder 82 through a central opening 103 in the upper head of the cylinder 82. The cross head 100 is retained in place on the stem 101 bythe nut 104. The cylinder 82,is provided with ports 105 and `106 respectively located above and below the limits (5f/travel of the lpiston 102 and connected with conduits 107 and 108, respectively, (see Fig. 12). Each of these conduits includes a flexible section andthe respective conduits are connected with opposite ends of a control valve 109 which in turn is connected by suitable pipes 110 and 111l with a source of pressure fluid supply 112. When the piston 102 .is in the lower part of the cylinder 82 as a result of the action of pressure fluid supplied to the upper part of the cylinder from the valve 109 through the conduit 107 and the port 105, the half sections of the gathering receptacle 96 will be kept closed. As shown in Fig. 13, the valve 109 may be of a usual slide valve type of construction, having a piston valve 231 pressed at one end by a com pressed spring 232 to position to establish communication between the pipes 110 and 107 and provided at its opposite end with a .stem 113 pivotally connected with a pivotally suspended lever 113a carrying a cam roll Y 114 in contact with a cam 115 on the cam' shaft 60. The piston valve 231 is adapted when actuated by the cam 115 to shut olf communication between the pipe 110 and the conduit 107 and to.simultaneously establish communication between the supply pipe 110 andthe conduit 108 and to vpermit exhaust of pressure iluid from the'conduit 107, whereby the piston 102 will be raised in the cylinder 82 and the half sections of the gathering cupv will be swung apart about the axis of the tubular member 85 from the closed position shown inFigs. 8 and 10 to position to discharge the contents thereof. As soon as,

.. nected by branch conduits 116 and 117,'re-

s ectively,l with upstanding valve casings 118, tlie connections of the branches 116 and 117 with` the casings 118 being at the sid'es of such casings and above seats, as at 120 fory downwardly opening tappet valves, as 121. The ta pet valves-have stems122 extending from t e tappet valve casings to positions close to and underneath the contact portions of tappets 123-which 'are pi'votallyv supported at the outer ends of the aforesaid arms 83 of the body of the gathering head on-a shaft 145. Springs 124 are-coiled aboutthe stems 122 between stops 125 on the upper end portions of the stems 122 and the upper ends of the tappet valve casings'and yieldingly maintain the tappet valves against their seats. The valve casings'118 are supported on upturned arms of substantially right angular tubular members .l 126, respectively. The

-members 126 have substantially horizontal arms 128 and 129, respectively, extending edge portions of the recesses 133 by the action of pressure fluid admitted through the pipes 134 into the cylinders 130 outwardly of pistons 135 in such cylinders. The pistons 135 are secured firmly to the members 128 andthe branch conduits 116 and 117 include flexible sections as clearly shown in Fig. 9 to permit the required axial movement-of the members 128.

As shown in Fig. 12 the pipes 134 may be Ilm with the longitudinal suction grooves 137 which are provided in the bore of the gathering cup at the inner edges of the contacting faces of the sections thereof whenl such gathering cup is closed, as shown' in Fig. 8. The engagement of the members 128 and 129 with the sections of the cup also aids in supporting "such sections in the sections 95 of the cup holder so that upstanding beveled flanges 138 on the head portions of the cup sections 96 will be maintained firmly in.

contact with the beveled walls of grooves 139 in the inner surface of the lhead portions 94 of the cup holder. However, the principal means for holding the cup sections removably in place in the sections of the-"cup holder are substantially semi-circular'fasten.- ing members 140. The fastening members 140 have holding screws 141 threaded through their web portions into engagement with indentations 142 in the holder sections 95 and each has inturned fingers 143 at' the ends of its arms in engagement with suitable depressions 144 in the outer wall'of the assoresem -ciated cup section 96 adiacent to the side been loosened, the fastening members 140 may be swung downwardly and thus detached from the cup holder sections and the sections of the atherin cup then may be withdrawn from t e cup older when the supply of pressure fluid through the pipes 134 to the cylinders 130 has been discontinued and the members 128 have been moved outwardly to release the head portions of the cup sections 96. Cup sections of various lengths andinternal shapes and having lower end portions of various shapes and slzes may be used in terchangeably with the same cup holder.

The valves 121 normally are held closed by the springs 124. Suction in the gathering cup will take place only when the valves 121 have been forced downwardly from their seats. Such suction will be instantly applied when the valves are open and instantly stopped when the valves are closed because 25 of the proximity of the valves to the place of application of the suction within the cup. The tappets 123 are arranged to be actuated simultaneously to open the valves 121 when the shaft 145 is rocked in one direction. The shaft 145 is journaled in aligned bores in the arms 83 and extends transversely across the arm 30 above a space that is cut away at 146 in the bottom or web of the arm 30 to afford clearance for the swinging movement of a downwardly extending rocker arm 147 on the shaft 145. The rocker arm 147 is pivotally connected by a rod 148 with a downwardly extending arm 149 of a bell crank 150.

As best seen in'Fig. 5, the bell crank lever 150 is fulcrumed on a horizontal pivot member 151 at the upper end of a supporting arm 152 on the gathering head carrying arm 30. The bell crank lever 150 also includes a rearwardly extending arm 153 which is connected by a ball and socket joint 154 with the forwardly extending arm 155 of a bell crank lever 156, which is fulcrumed on a horizontal stud 157 at the upper end of a block 158. The block 158 has vertically's aced sleeve portions 159 and 160, respective which slidably embracei a vertical supporting and guiding rod 161.` The 'rod 161 is journaled .at its upper and lower ends in vertically aligned bearings in horizontal arms of brackets 162 and 163;"respectively, carried by an upright standard 164. The latter is 'secured rigidly in place on the top of the case 35, all as clearly l shown in Fig. 6. The bell crank 156 includes a downwardly and rearwardly extending arm 166 which is connected by a horizontal pivot element 167 with a slide block 168 vhaving a pair of arms arranged to straddleand slidingly embrace a guide rod 169,'. The guide rod 169 is maintained in spaced parallel relation with the guiding and supporting rod 161 by means of a pair of upper and lower cross bars 170 and 171 sothat the blocks 168 and 158 and the bell crank 156'may slide ver-K tically as a unit between the members 161 and 169, but are prevented from swinging abou the axis of the member 161 independently of the member 169. The block 158 is carried by i an arm 172 which is secured to the upper end portion of the shaft 32 and `thus is prevented from moving vertically independently of the shaft 32. Consequently, when thelshaft 32 moves vertically, the bell cranks 150 and 156 y and the blocks 158 and 168, together with the arm 172 on .which the block 158 is supported,

and the rod 148 that' connects the bell crank 150 with the tappet actuating rock shaft 145 will move vertically in accordance with the vertical movement of 'the shaft 32 without any relative change in the positions of these respective members. Also, the. turning movement `of the shaft 32 about its axis to.

swing the arm 30 horizontally will be accompanied by a swinging movement of the block 158 and the parts which are connected therewith about the axis of the guiding .and supporting shaft 161 without any relative change in the positions of th respective pivotally connected members. However, actuation of t-he rod 148 to open the tappet valves 121 or to permit closing thereof will take place when the shaft '161 is rotated independently of the shaft 32. Such independent rotation4 of the shaft 161 will cause the member 169 to swing about the. axis of the shaft 161 from the position shown iii Fig. 5 toward the 4arm 30. The slide block 168 will move downwardly independently of the block 158 as the horizontal distance between the axial line of the fulcrum 157 of the bell crank 156'and the center of the ball joint 1,54 decreases. The bell crank 156 meanwhile is swung about the axis of the member 157 so as to raise the arm 153 and the vball joint 154 and thereby tocause a pull on the rod 148. This pull on the rod 148 is suicient to rock the shaft 145 as re luired to openingof the tappet valves is caused by the contact ofaperipherally adjustable cam block or dog 173 on a disk 174 with a cam roll 175 on an arm 17 6 that is secured to a short vertical rock shaft 177 from which motion is transmitted to the shaft 161 through a rocker arm 178 on the shaft 177, a link 179 and a rocker arm 180 on the shaft 161 (see'Figs. 3.

5,' 6 and 7). The camvblock 173 may be adjusted around the periphery of the disk 174,

which is secured on the cam shaft 60, to time the opening of the tappet *valves in relation to the other cam actuated operations' of the apparatus and particularly with relation to the Y movements of the gathering head and the mechanism for opening and closing the sections of the gathering cup. The tappets and the operating mechanism therefor as 'menactuated tappet valve operating mechanism as shown in Figs. 2 and 3 to assure this result. The -cam block 181 also is adjustable about the periphery of the disc 174 so that the instant of cessation of the application of suction to the gathering cup may be adjusted in respect to the time of beginning of the application of such suction.

The apparatus includes a severing mechamsm for cutting the glass between the suction cup and the supply body withinthe forehearth after the gathering cup has been filled "by suctionwhile in its gathering position substantially as shown in Fig. 4 and has been raised through the gathering opening 11.y Such severing mechanism preferably com-j.

prises a pair of V-notched shear blades 182 which. arecarried on the shear arms 183 pivoted on the vertical pivot member .184 for closing movementabove the gathering opening 11. The verticalpivot element 184 is carried by a supporting head 185-of a slide block 186 which is retained against the inner side wall lof the case by a pair of guiding and retaining anges or plates 187 on-the case 35.

' The block 186 may be adjusted vertically to vary the height of the plane at which the shear blades'will close. This adjustment may' be effected by 'means' ofan adjusting screw 188 which threadedly engages a vertical bore 189 in the slide block 186'and is journaled in vertical opening in a lug 190 on' the adjacent side wall of the case 35, being held against axial movement by a Stop collar 191 above, and a hand' wheel 191a below the lug 190. The

guides 187 will prevent turning movement of the block 186 aboutthe axis of the adjusting screw 188 as the block 186 is moved verticallv.-

The shear armsmay be actuated to open and close the shear blades at the proper times in 'any suitable known manner. Suitable mechanism for actuating the shear .blades may comprise a cylinder 192 having a piston 193 reciprocable therein and connected by a stem 194 with a cross piece 195. The latter extends between the adjacent ends of pivoted links 196 which are connected -at their other ends to out-turned arms' 197 on the shear carrying levers 183. Movement of the piston 193 in the cylinder 192 from the position shown in Fig. 4 toward the shear blades will cause the shears to close and cut through theglass between the charge within the gathering cup and the glass supply body in the forehearth while a return movement of the piston 193 in the cylinder 192 will cause opening of the shear blades. The reciprocation of the piston in the cylinder 192 may be eected by'alternately admitting and exhausting air under pressure to the opposite ends-lof the cylinder 192 at times which are selected in respect to the times of the gathering operations of the cup. The application and exhaust of pressure uid 'to and from the opposite ends is pivotally connected with the lower end of i a ,substantially vertical pivoted arm 20311. The latter carries a cam roll 203 in contact with the peripheral edge of a cam 204 on the cam shaft 60. As shown in Fig. 2, the arm 203e is supported at its upper end on a horizontal pivot 300 which is carried by a fixed support 301. rlhe valve Within the casing 198 is urged by a spring 205 toward the cam 204, and when the cam 204 will permit, the spring 205 functions to move the valve to position to shut olf communication between the supply pipe 199 and the pipe 201 leading to the inner end of the shear cylinder 192 and to establish communication between the supply pipe 199 and the pipe 200 leading to the outer end of the cylinder 192 so that the shear j blades will be closed. The valve 198 of course functions to permit exhaust from each pipe 200 and 201 when such pipe is o ut of communication with the supply pipe 199. The valve`then will again be actuated by the cam 204 against the action of the spring 205 to discontinue the flow of pressure Huid through the pipe 200 to the shear cylinder and to cause pressure fluid to pass through the pipe 201 to lthe shear cylinder. The cam 204 is shaped so that the shears close quickly once during each complete cycle of rotation of the cam about the axis of the cam shaft 60, after which the shears open and remain open for the remainder of such cycle. As shown in Figs. 2

and 12, the cam 204preferably comprises a hub disk 204e fixed to the shaft 60 and a cam disk 2045 adjustably secured to the hub disk 204a, as at 232, so as to permit the cam disk to be adjusted angularly about the axis of the shaft 60. .-The time `of `'closing of the shearl by any suitable support 207 adjacent t`o the case 35. The motor preferably has a motion transmitting connection with the cam shaft 60 through a sprocket 208 on the motor drive shaft, a chain 209 between the sprocket 208 and a sprocket 210 on a second motionshaft 211, and aworm on a second motion 211 in engagement with a worm wheel 212 (see Fig. 4) on the cam shaft 60. The cam shaft 60 may carry a sprocket 213 connected by a chain 214 with a stub shaft 215. The stub shaft 215 carries a bevel gear 216 in mesh with a bevel gear 217 on a shaft 218 that extends parallel with the glass circulator Shaft 19. The shafts 19 and 218 are connected to rotate in synchronism by a `sprocket and chain transmission'mechanism such as indicated at 219 in Fig. 2. The shaft 218 is journaled in bearings on a suitable bracket or frame structure 220 secured to the forehearth casing. ,The shaft 215 likewise isournaled in a suitable bearing connected with the forehearth casing, and the shaft 211 preferably is journaled in suitable bearings in side walls of the case 35.

The cam shaft 60 also may carry a cam i 221 for tripping a .valve 222 (see Figs. 3 4and 12) forl controlling the flow of operating pressure. fluid from a supply pipe.223` to a delivery pipe 224 leading to operating struc-- ture of an associated vglassware forming or fabricating machine (not shown), whereby the operations of the forming machine .will be synchronizedv with the cam actuated oper-4 ations of the improved feeding apparatus.-

The valve 222 is shown only diagrammatically, since it may be of any suitable known construction, such asis well known in-` the art.

It is within the purview of the invention that all of the cams which are included in the hereinbefore mentioned apparatus shall be capable of being set so as to variably time the operations of the parts to be actuated thereby relatively to one another as desired. The positions in which the cams are shown in Fig. 12 and in certain of the other figures of the drawings are notnecessarily the positions of such cams during thel operation of the machine. Certain of such cams have been specifically describedand illustrated as comprising structure which permits angular adjustment thereof about th axes of their supporting shaft. If desired, each of the cams may be .provided with an adjusting 'mechanism such as is illustrated and de# scribed in the pending ap licationof Karl before'the gathering head reaches its lowest justed about the axis of its shaft during the rotation of the shaft and without stopping the operation of the improved machine.

A cycle of operations of the improved apparatus may be described as being substantially as follows:

The motor 206 is started to cause turning of the cam shaft 60 and the glass circulator operating shaft 19. Assuming that the gathering head is in the dotted line position of Fig. 4 at. the beginning of a cycle of operations, the rotary movement of the cam shaft 60 turns the cam 59 so that the gathering head is permitted to move downward substantially to thefull line position of Fig. 4 and toremain temporarily in that position, the lower end of the closed gathering receptacle then dipping slightly into the glass in the forehearth. The lower limit of the downward, .Y

-ed'by manipulating the nuts 54 according to the glass level in the forehearth and according to vthe lheight of .the particular gathering receptacle that is in use at a given time. The cam block 173 on the disc 17 4 is timed to cause opening of the tappet valves 121 at a predetermined time with respect to the termination of downward movement of the gathering head, which may be immediately position, at the instant the gathering head reaches its lowest position, or at an time thereafter while the gathering hea is at rest in its lowest position. The opening of the tappet valves results in the instantaneous application of suction to the gathering space within the closed gathering receptacle so that molten glass will be drawn from the supply body in the forehearth into the gathering receptacle until the ^latter is completely filled. The turning of the cam 59 about its axis of rotation then will cause the gathering head with the filled gathering cup, to move v upward from the full line position of Fig. 4 toward the dotted line position of Fig. 4. The shear cam is adjusted about the' axis of rotation of the cam shaft 60to cause severance of the connecting glass rbetween the gathered charge and the supply body at a time which maytbe selectedJ with relation to 115 the termination of upward movement of the gathering head in order to produce a desirable` shape at the lower 'end of the ath# 'ered charge. For example, the shear b ades may close while the gathering head is moving upwardso that the gathered charge held by the cup will have its lower end portion tapered or .whittled bythe co-action between the closing` shear blades and the .upward movement of the gathering head. The cocks 256 may be adjusted to cause the closing shear blades to cut through the rising glass at a decreasing speed, which will further vary the shape of the lower end of the .mold charge. Y Or, the shear blades may be .1,39

timed to close after the gathering head has reached its highest positions so that thegathered charge will have a blunt lower end. The distance from the lower end of the ygathering receptacle at which the shear blades sever the glass may be varied so that more of less glass depends from the gathering receptacle after severance, which will have the veEect ofchanging the weight of the gathered charge and also will have a slight effect on the shape of the lower end portion of the charge since the central portion of the gathered charge will be hotter than the outer portion `thereof and its resultant tendency to move downwardly by gravity will have increasing eifectiveness as the distance of the lower end of the gathered chargefrom the lower end of the gathering receptacle increases.

After the gathering head is in the dotted line position of Fig. 4 and the charge in the gathering receptacle has been severed from 'the supplyl body, the cam 71 will function to swing t e gathering head laterally toward a discharging position over a mold on the mold table. Assuming that the stop 76 is retained in its inactive or non-obstructing position by air pressure at the time of the ateral swinging movement of the gathering head, the gathering head will swing across the intermediate station above the cullet chute 73 to the mold filling station and then will pause at the mold illng station. The valve closing-'cam block 181 is adjusted on the disc` 174 with relation to the time ,of arrival of the gathering'head at thedischarging station and in synchronism with lthe movements of the mold table so that a mold will be disposed in a position to be lilled from 40 the gatherin head at the time the tappet valves are c osed to release the gathered charge from the iniiuence-ofsuction. Also, the cam disc 1156 is adjusted about the axis of rotation of the cam shaft to effect opening of the gathering receptacle at a time that is related both to the arrival of the gathering head at the filling station and tothe closing of the suction controlling tappet valves. The cessation of suction in the gathering h ead and the opening of the gathering receptacle may take place simultaneously and the gathered charge will fall by gravity into the waiting mold or the suction may be cut off after the arrival of the gathering head at the mold lling station and immediately before o-r after the beginning of opening movement of the gathering receptacle.

After delivery of the gathered charge, the sections of the mold receptacle are closed and thegathering head is swung quickly from thegdotted line osition of Flg. 3 tol the-f ull line position ofpFig. 3 and the dotted line position of Fig. 4 and a new cycle of opera.- tions is initiated. A

lIn/'the event that the feeder should bem operation while the associated shaping machine is inactive and it should be desired to deliver the gathered charges into the cullet chute 7 3 at the intermediate station, `the valve 229 is closed so that the stop 76 will be maintained in position to stop the gathering head at the intermediate station above the cullet chute and indue course of time during each cycle of operations, the tappet valves will be closed andthe gathering receptacle -will open todischarge the gathered charge into the cullet chute. This will take place until the valve 229 has been opened to effect removal of the stop 76 from its active position to its non-obstructing position andth'ereafter the gathering-head will swing in each cycle of operations from its position above the gatheringopening past the intermediate station to the more remotemold lilling station. It is`obvious that the intermediate station may be above a suitable 'chute or transfer device for filling molds on a second mold v table instead'of `for delivering such charges to a cullet chute sthat the same feeding apparatus may'be used at 'different times to fill molds on two 'different mold tables. For example, valve 229 may be closed and opened periodically by'suitable cam means timed to function at appropriate times in respect to the charge gathering and discharging means so that the gathered charges will be delivered at the intermediate station and the moreremote station alternately. Il.

The action of the glass circulatorin the glass inthe forehearth will positively preventv any' stagnation of chilled o r relatively cool'glass in the frotpart of the forehearth orat the gathering station so that the mold charges which will be gathered by the use yof the improved gathering apparatus will be of symmetricaly temperature, viscosity and condition and because of the adjustments and beneficial` features which have just been' pointed out inthe description of the operay /J tion of the apparatus, will be of uniform and compact shape in successive-cycles for the same adjustments under the same conditions Without preventing regulations within limits in dierent cycles of the shapes of the lower ends andthe weights of such mold charges.
